Plantation of Native Swintonia floribunda Griff and its Contribution to Carbon Storage

Purpose: The study aimed to estimate the biomass and organic carbon storage of Swintonia floribunda Griff, a fast-growing and ecologically significant native tree species in Bangladesh, known for its carbon sequestration potential. Methodology: A non-destructive, systematic methodology was applied to assess tree parameters, including diameter at breast height (DBH), height, and mean annual increments across age groups ranging from 15 to 55 years. Findings: The findings revealed that 50-year-old trees recorded the highest DBH (65.45 cm) and height (31.52 m), while 15-year-old trees showed the highest mean annual diameter (1.75 cm) and height (0.92 m) increments. Biomass and carbon content ranged from 418.80 kg/tree to 5,253.60 kg/tree and 209.40 kg/tree to 2,626.80 kg/tree, respectively. Statistical analysis confirmed significant variation (p < 0.05) in biomass and carbon stock among age classes, with a strong positive correlation (r = 0.99274) between age and carbon storage. The study provides empirical evidence of the species’ capacity to enhance carbon storage over time, offering valuable insights for policymakers, conservationists, and forest managers. Unique Contribution to Theory, Practice and Policy: Its unique contribution lies in promoting a sustainable, non-destructive approach for assessing carbon stocks in endangered native species, supporting climate change mitigation and sustainable forest management in Bangladesh.
